TRAVERSE-MOTION FOR YARN-SPINNING APPARATUS.

Specification of Letters Patent.

Patented Nov. 30, 1909.

Application filed February 13, 1909. Serial No. 477,532.

To all whom it may concern: I

Be it known that I, ALoNzo E. RiioAoEs, a

citizen of the United States, and resident of llopedale, county ofWorcester, State of Massachusetts, have invented an Improvemerit in'lraverse-Motions for Yarn-Spin- 'ning Apparatus, of which the followingdescription, in connection with the accompanying drawing, is aspecification, like characters on the drawing representing l ke parts.

This invention relates to apparatus for spinning yarn, and it has forits object thetion is of very simple construction, there befing but asingle connection between the builder-motion and the usual rockerthrough ,which the vertical movement of the ring-rail is controlled. I

The construction and operation of the builder-motion herein are suchthat the yarn I .is laid at the beginning of the winding with g theminimum traverse, and such traverse increases automatically andgradually through V 'out the winding operation, but in order to give theproper and desired conformation to the yarn mass on the receiver orbobbin the gain starts at the maximum and gradually dccrcases throughoutthe winding.

V l t is well known to those skilled in the art .tlnitithe same quantityof yarn is laid at each traverse, hence a shorter traverse lays the yarnmuch more closely than a longer traverse does, so that. at the beginningof the winding, when the traverse is short, there is atendency in theyarn laid on one traverse to roll over the yarn laid .on the previoustraverse, particularly at the lower end of the ,traverse, so that thereis more or less interi ference between the two portions of the, yarn,causing it to draw ofi' improperly and unevenly in the shuttle.

With a gradually increasing traverse the increment of increase onsuccessive strokes of the ring-rail is sosmall that such rolling over orcrowding of the yarn cannot be obviatcd by the traverse alone, and in mypresent invention l overcome the obj cction noted by starting thewinding with a maximum gain. By so doing I carry the ends of successivelayers of yarn far enough to extend beyond those immediately preceding,and thereby lay each layer properly and evenly upon the yarn-receiver,without any rolling over or crowding of the turns of one layer into the.turns of the layer beneath, and

.the yarn in consequence draws ofl' evenly and without obstruction, inthe shuttle, down to the very beginning of the winding if need be. Thecompleted yarn-mass tapers gradually up to the body portion, at itslower end, and tapers gradually in the opposite direction at the top ofthe body-portion, obviating the formation of a pear-shaped yarn-mass,which shape, is highly objectionable. \Vhile the maximum gain at the beginning of the winding obviates the fault referred to it is necessary toeffect a gradual decrease of the gain during the winding, and

I have made provision therefor, as will appear hereinafter. Vere it notfor such gradual decrease of the gain the structure embodying myinvention would so. operate that the winding would be completedwithrelatively a very small quantity of yarn laid.

The various novel features of my invention will be fully described inthe subjoined specification and particularly pointed out in thefollowing claims.

Figure l is a front elevation of a sufficient;

portion of a spinning-frame with one prac-' .tical embodiment of myinvention applied thereto, the ring-rail being shown somewln t above itslowest point, but otherwise tl e mechanism is in readiness to begin thewindmg of a set of bobbms; Fig. 2 1s a transverse section on the line22, Fig. 1, looking toward the left, showingthe builderanotion and theactuating cam therefor in side elevation; Fig. 3 is an enlarged detail,partly broken out, of the builder-arm and parts carried thereby, butwith the winding-drum and its gear removed; Fig. 4 is a transversesection on the line 44, Fig. 3, looking toward the right, but with thewinding-drum and its gear in place; Fi 5 is a similar view on the line5-5, also looking toward the right; Fig. 6 is a left-hand elevation ofthe builderarm, showing the ratchet by means of which the traverse isvaried, and the shield to gov- In the present'embodiment of my inventionthe ring-rail is raised by a suitable lifting-weight and depressed by orthrough the builder-motion, the winding mechanism letting off the chainfrom the winding drum or barrel to govern the gain of the traverse,while the traverse itselfis gradually increasedby a gradual bodilymovement of the drum from the fulcrum of the builderarm.

Referring to Fi s. 1 and 2, the spindle-rail 1, rotatable spind es 2,the vertically-reciprocating ring-rail 3 provided with usual rings 4,the lifter-rods 5 (one being shown in Fig. 1) the rocker 6 cooperatingwith the foot of the lifter-rod and provided with a weight 7 to elevatethe ring-raiL-and the rocker-arm 8 rigidly attached to the rocker andtransmitting reciprocating movement to the other lifter-rods through thelink 9, may

be and are all substantially of well known or usualconstruction insplnning or similar apparatus.

flexible connection, preferably a chain 1Q, as herein shown,iscOnne'cted at one end tothe branch 11 of the rocker 6 and is led overa guide-sheave 12 mounted in a swinging support fulcrumed at 12 on themam frame and thence to a winding-drum or bar-- rel 13, and attachedthereto, said drum having attached to or forming part of it a concentricgear14, said drum and gear-being rotatably mounted on a laterallextended stud 15.fixed on a traveler 16, to be referred to again, whichacts as a traverse-changer.

T e builder-motion herein shown includes a builder-arm 17 fulcrumed at18 on the main frame and provided with a roller or other stud l9constituting a follower to cooperate with an actuator, shown as atraverse-cam 20havingthree points, Fig. 2, the weight 21 connected withthe builder-arm counter-balancing the weight of the parts thereon andmaintaining the follower in engagement with-the cam.

As shown in'Figs. 2, 3 5, the builder-arm for the greater portion of itslength isv shaped in cross-section, the u per and lower parallel flangesbein longitu inally grooved at22 to formgui eways for the top and bottomof the traveler or traverse-changer 16, as clearly shown in Fig. 4:,retaining plates 23 maintaining the traveler in osition while permittingmovement thereo lon- 'gitudinally of the builder-arm. Manifestly thebuilder-arm has a constant stroke, hence it follows that the farther awathe traverseshifter 16 is moved from the ulcrum 18 the greater theamplitude of movement of the ring-rail, and vice versa, so that if thewinding operation starts with the traverse-changer .rin -rail.

, at its extreme inward position, Figs. 2 and 3,

the minimum traverse will be g ven to the be starting point for thetraverse-changer 16 is determined by means of a headed stoppin 24adapted to be inserted in any one ol a series of holes 25 (see dottedlines Fig. 2-5,) in the top flange of the builder-arm, the lower end ofthe pin being adapted to engage an abutment 26 on the traverse-changerand thereby limit its movement when windingback is efi'ected.

By placing the stop-pin in one of the holes more to the left, Fig. 3,the starting point of the ring-rail will be raised more or less withrelation to the butt or head of the yarnrcceiver or bobbin, to therebyadjust, the beginning of the winding of yarn thereupon, and after thestop-pin has been properly set the starting point of the winding willremain the same as one set of bobbins after another is wound, thetreverse-clianger .113 being stopped at the same point upon windingback.

Inasmuch the traverse-elmnger moves outward along the builder-armthrougluuit the winding the guide'sheave 12 is pivot ally mounted toavoid any cramping or twisting of the chain 10.

Referring to Fig. 2 it will be seen that the chain 10 leads tangentiallyfrom the periphery of the drum Iii-up to the sheave 12, which swings onthe stud 12*, and as the traverse-changer moves outward the chain willgradually. ap roach a vertical line intersecting the stu so that as theangle between the chain and such vertical line gradually decreases therewill be a slight decrease in the distance between the sheave. l. and thepoint on the drum at which the chain leaves So, too, as the traverse- Ichanger continues its outward movement beyond-the vertical line throughthe stud 12* the distance between the sheave 12 and the. point at whichthe chain 10 leaves the drum will slightly increase. Hence, during thegradual decrease in such distance there will be a gradual increase inthe gain, and thereafter a gradual decrease in the gain the distancereferred to increases, but in each case in actual practice suchvariations in the gain are so small as to be hardly appreciable.

As the gain in the apparatus forming the subject-matter of thisapplication is started at a maximum, and gradually decreased throughoutthe winding, as will be explained hereinafter, it is only necessary tomake the initial maximum gain large enough to compensate for thevariations just pointed out, so that the change in the position of thetraverse-changer with relation to the stud 12* can in practice bedisregarded.

The builder-arni has transverse end-plates 27, 27 secured fixedly to theup )er and lower flanges, which plates provide earings for 'an elongatedshaft,28 spirally threaded at 2 9 to pass through and engage a threadedhole 30, Fig. 4, 'in the traverse-changer. so

i upright rod 33 held adjustably that rotation of said shaft will slidesaid traverse-changer longitudinally along the builder-arm. I At itsouter end, beyond the plate 27*, a ratchet 31 is secured to the shaft28, the ratchet being intermittingly engaged and rotated step-by-step bya pick-pawl 32 fixedly connected with the lower end of an by set-screw34 in a holder 35 pivoted at 36 to a bracket 37 secured to the mainframe, Figs. 1 and 2. On each up-stroke of the builder-arm the pick-pawlengages and advances the ratchet, and thereby turns the shaft 28 toeffect a slight outward movement of the traversechanger 16 along thebuilder-arm, but as the pawl is arranged to impart a graduallyYlecreasing advance movement to the ratchet it is pivotally hung, as hasbeen described, 0 for reasons which will appear hereinafter.

Astop 38 on the bracket 37 is arranged to cooperate with the holder 35and prevent movement of the pick-pawl 32 to the right, viewing Fig. 1,while said pawl can move in the opposite direction about the fulcrum 36as a center.

The builder-arm has rigidly attached. to it by lateral brackets 39 alongitudinal rack- 1 bar 4O offset far enough to bring its teeth intomesh with" the drum-gear 14, so that as 'theftraverse-changer 16gradually moves the a iiidingrdrum 13 toward the free end of thebuilder-arm the cod eration of the rack-bar and said gear 14 wil slowlyrotate the drum 13b to letoif the chain 10 and effect the principal 5gain of the'traverse. Thus the angular movement of the drum. about itspivotal support 15 determines,'in the main, the amount of gain, suchmovement. of the drumovercoming or compensating for the slightvariations in'the gain due to the change in the posiiion of the drumrelatively to the stud 12", ereinbefore referred to, and the amplitudeof angular movement of the drum upon the support 15 is directlydependent upon the extent of eachadvance of-the traversechanger 16 awayfrom the fulcrum 18 of the builder-arms So, too, such advance willdepend directly upon the rotative'movement.

of the threaded shaft 28 imparted to it by each operativeengagement 0the pick-pawl and the ratchet 31, and by making the ini- -tial ,ormaximnmaction of the pawl and ratchet large enough the gain as a wholewill be co trolled absolutely by or through the angularmovements of thedrum.

Now the lengthJof the traverse depends upon the position ofthe'traverse-changer with relation to the fulcrum of thebuilderarm,-and' as the traverse-changer is moved step-by-step: awayfrom such fulcrum from the. beginn V operation it will'be obvious thatthe traverse gradually increases in length, butof course fifi with avery small increment. This increg ing to the end of the winding ment isnot of itself sufficient, with the slow. letting off of thechain,ordinarily resulting from the action of the winding mechanism to lay theyarn properly at the beginning of the winding, as has been stated, andtherefore I have provided means to start the winding with the maximumgain and gradually to decrease the gain automatically as the windingproceeds at the same time overcoming or compensating for theslightirregularity or variation in the gain previously noted.

A slightly bent lever 41 is adjustably fulcrumed at 42 on thebuilder-arm between its upper and lower flanges and near the plate 27,the under edge of said lever resting upon a rounded and rearu'ardlyextended cam-rib 43 on the traverse-changer 16, the fulcrum-stud 42-being fixed in posi- -tion in the vertical slot 44 by a nut 45, see Fig.5. vSaid lever 41 extends along the builder-arm nearly to the end plate27 and is then turned laterally to present a foot 4-6, which is archedto extend across and clear the threaded shaft 28, as clearly shown inFig. 5, the extremity of the foot haviag a slot 47 in which is secured aheaded stud 48, held in adjusted position injthe slot by a check-nut 49.The foot 46 is long enough to bring the stud beyondthe edge of'lhc endplate 27*, as shown in Fig. 3.

The ratchet 31 has an elongated hub 31*,

Fig. 3, embracing the projecting end of shaft 28, and upon said hub isrotatably mounted a collar 50, separately shown in Fig. 7, having a head51 provided with a radial extension 52 having a slot 53 into which thestud 48 extends, the headed collar forming a support for the shield.

The shield 54 is shown as curved and overhanging the ratchet 31 at theright of the pick-pawl 32, Fig. 1, the shield being mounted on an arm 55secured to or forming part of a hub 56 which embraces the collar 50between the head thereof and the ra-tchel. said hub carrying a.set-screw 57, seedotted lines Fig. 6, by means of which the hub and thecollar are fastened together to turn as a unit.

In Figs. 1, 3 and G the shield is shown in .the position assumed at thebeginning of the Winding operation, the traverse changer 11) then beingat the right-hand end of its stroke, nearest the fulcrum of thebuilderarm, and the lever 41 has its foot 46 and the stud 48 in theirlowest positions.

Referring to Figs. 1 and 6 it will be apparent that when the shield isin the position shown the pick-pawl 32 will exert its greatest effectupon the pawl 31 and will effect the greatest angular movement thereofon the up-stroke of the builder-arm, because the maximum number ofratchet teeth are exposed to the action of the pawl as the builderarmoscillates, If, however, the

shield 54 be gradually moved to the left, l igs. l and t3, the number ofratchet teeth exposed to the action of the pawl will be decreased, andconsequently the pawl will etl'ect a gradually decreasing angularmovement o the ratchet and. connected parts. That is, ihe shield will bebrought into engagemcnt with the pick-pawl and will push the latter awayfrom a vertical line through the axis of the shaft- 28, so that the pawlcan take up a less nui-nber of teeth of the ratchet 31. and suchmovement of the pawl by the shield is permitted by mounting the pawlrod33 to swing about the pivot 36 as a fulcrum. As the shield may be set byhand, through the medium of the set-screw 57, the

- angular movement of the ratchet at the beginning of the winding can beincreased or decreased at will, according to circumstances, and toproperly compensate for the variation in the gain due to out 'ardmovement of the drum, but whatever the initial set of the shield therewill be a gradual diminution in the step-by-step movement of the ratchetfrom the maximum. 5

Inasmuch as the rotation of the ratchet controls not only the advance ofthe traverse-shifter 16 but the rotation of the drum l? to cttect thedesired gain of the travverse the. operation will be understood with abrief description of the winding, starting at the commencement thereof.

()n the up-stroke of the builder-arm 17- the" as the cam-rib 43 isthereby moved to the left, Fig. 3, the lever 41 will be acted upon andits foot. 40 will be given a slight rise. This causes .the stud 48 toimpart a small angular advance to the collar or shieldsupport: 50 m thedirection of the arrow 100,

' Fig. ti, and the shield 54 is moved in the same direction, to uucoveasmaller portion o'l' the ratchet. 31 to the action of the pickpawl 32.Consequently the angular movement of the ratchet will radually decreasein amplitude as the winking proceeds, and as the intermittent rotationof the threaded part 25) of the shaft 28 is correspondingly decreasedthe feed movement of the traverse-changer 16 gradually decreases.

The shorter the feed of the traversechanger the less amount of chaingiven off from the. winding drum 13, and therefore the less the gain, sothat while the gain starts at its maximum it is gradually decreased asthe winding progresses, notwithstanding the change in the position ofthe drum relatively to the stud 12*, and the traverse g 'aduallyincreases, due to the feed of the traverse-changer away from the fulcrumof the builder-arm. The diminishing gain thus acts in connection withthe increasing traverse to lay the yarn upon the yarn-receiver or bobbin1), Fig. 8, with a taper from the lower end of the yarn-mass upward, asat m, to the substantially cylindrical body portion m of the yarn-mass,with an inward taper m" at the upper end thereof. A full winding of yarnis secured, with the yarn-mass of the desired shape, and so laid thatthe varn draws oti' smoothlv and evenly down to the very beginning ofthe 'windmg, the layers at the beginning of the the lever 41, and topreserve the proper relation between such parts the fulcrum 42 of thelever 'will be slightly raised in the slot 4st.

By setting the stud 48 toward or away from the center of the shaft 28the angular movement of the shield 54 will be increased or diminished,respectively, for a given rise of the stud as the lever 41 1s swung upabout its fulcrum by the feed of the traversechanger, to thereby retardor hasten the rate of change in the gain As to the traverse, while it isgradually increasing throughout the. windin its rate of increase isgradually decreasing, for it. must be remembered that the steps by whichthe traverse-changer is fed toward the outer end of the bnilde '-arm aregreatest. at the beginning of the winding and gradually decrease. inlength as such winding proceeds.

in view of the foregoing description and explanation of the operation ofcertain parts of theapparatus, having more particular reference to thegain of the traverse and its control, it will be manifest that the gainis controlled, broadly, by means mounted on the builderarm and actingupon the ringrail through the connection between the lat- :ter and thebuilder-arm.

This apparatus does not wind whatis technically known as a bunch by apreliminary windin of the yarn, as is done by some otherbuilder-motions, the yarn-mass being completed by a main or serviceWinding, but in actual practice the first few layers of yarn lald uponthe yarn-receiver by the present apparatus can in practice be utilzed inas feeler loom to perform the funcparting from the spirit and scope ofmy present invention as'set forth in the claims annexed hereto.
